Disk Control Frame
The disk control frame controls your disk array. It provides you with a
control panel, power supplies, controller boards, and your service
processor.
Figure 2. Disk Control Frame
There is no single point of failure in the disk array. It is designed with
redundant controllers and redundant power supplies, all of which can be
removed or replaced without interrupting access to your data. Only your
HP Service Representative can remove or replace hardware.
Control Panel
The control panel is your view to the disk array. Once the disk array is
powered on and running normally, there are no user operations required at
the control panel. The control panel will be discussed in further detail later
in this chapter.
